Fig. 22 illustrates a modification of themandrel shown in Fig. 13. Figs. 7, 8, 9, 10,11; 12, 13,14, 15 16 are drawn to an the collar against the tension of the spring 7c when said 'male portion K or K is moved along its shaft which are mounted the driving shaft Bfthe cam shaft 0, the cop carrying shaft D, and.

the shafts E, F, G, H, I, and J and the shipper rod J The shaft B has mounted upon one end thereof the pulley B firmly secured thereto, a portion of which is broken away in the drawing, and a loose pulley not shown, and

between the frames A and A has firmly secured thereon the spur gear wheel a which meshes into and imparts motion to the spur gear wheela mounted loosely upon the shaft E. The shaft B- also has mounted loosely thereon the spur gear wheels I), c, d, and 6, each of which constitutes, or is connected to, the female ortion of aclutch, with which one end or t e other of the male portion of a clutch, as K or K constructed substantially as shown in Figs. 7, 8 and 9, engages to compel said gears to revolve with said shaft B.

The female portions of the clutches connected with or forming parts of the gears b, c, d, and e consist of annular lips f havin a corrugated inner surface in the form 0 a series of inwardly dprojecting teeth as f shown in Figs. 10, 11 an The male portions K and K of the clutches are each composed of a sleeve is, the circular collar 7c, and the toothed collar k all made in one piece, the toothed collar k fitted to and movable endwise upon said sleeve k to a limited extent, and the coiled-spring 1c surrounding said sleeve k between the collars k and 76*.

k is to permit said collar to yield to cause an engagement with the female clutch member of the gearsb or e until the outlines of said female clutch member and said collar k coincide, when-the spring is will actv to force said collar 70 into said female clutch member.

The movement of said collar k upon said sleeve is limited by the pin k set in said collar 76 and projecting into the slot is formed in said sleeve. The sleevesk are connected to the shaft B so as to'be revoluble therewith and movable endwise thereon b' -means of a key k and asuitable k-eyway, al as shown in Figs. 7, 8 and 9.

The purpose of this movement of The teeth of the gear wheel I) engage with close proximity to said gear h engages the Figs. 1, 5 and 6.

' fixed positions, the collars Z, Z Z and Z each the teeth of the gear wheel b mounted upon and firmly secured to the shaft G as shown in The gear 0 engages the gear a mounted loosely upon the shaft E and provided with a sleeve-like hub c which projects through the frame A and has secured upon iBts outer end the gear wheel 0 as shown in The gear (1 engages the gear d mounted loosely upon the shaft E, and the gear e engages the gear 6 mounted upon and firmly secured to the shaft E as shown in Figs; 1 and 6. The shaft E has firmly secured thereon, just inside the gear 0 the pinion c which meshes into and imparts motion to the gear wheel 0 firmly secured upon the shaft C upon which is also firmly secured the cam L, as shown in Figs. 2 and 5.

The gears a and d mounted loosely on the shaft E have formed in their opposing faces, recesses or sockets, as shown in Figs. 11 and 12 to receive one or the other end of the male portion of a clutch K shown in Fig. 1, said male clutch portion being constructed, and connected to said shaft, substantially as shown inFigs. 7 ,8 and 9. i The gear 0 engages the gear g mounted loosely upon a stud 9 set in the elbow lever M mounted upon and adjustable about the hub a of the frame A and clamped in its adjusted position by the clamping bolt 9 set in said frame A and extending through the slot g in said lever as shown in Figs. 2 and 4. The gear 9 has secured thereto, so as to revolve therewith, the gear h which in turn engages the gear h, firmly secured upon the end of the shaft G. The gear h also secured upon said shaft in gear 46 secured to and mounted with the gear '6 loosely upon a stud i set in the lever N. The lever N in turn is mounted upon and adjustable about the hub i of the frame A and secured in the desired position by the clamping bolt i which passes through the slot 4. and screws into the frame A as shown in Figs. -2 and 4. The gear z" engages the gear j, keyed upon the end of the shaft D, in such a manner as to revolve therewith, and at the same time permit the said shaft to be moved endwise through-said gear, which is provided with a sleeve-like hub j, which projects through the frame A and has secured upon its inner end the collar 3' all as'shown in Fig. 2.

The shaft F has firmly secured thereon in provided with a sleeve-like hub projecting therefrom toward the right of Figs. 1 and 2, and between said fixed collars are loosely fitted upon said shaft the shipper arms m, m and m each provided with a sleeve-like hub rojecting toward the left of Figs. 1 and' 2. he forked end of the shipper arm m engages the circumferential groove between, the collars k audit of the clutch K on shaft B and its hub is provided with the lug a,

projecting below the periphery of said hub, as shown in Fig. 2. The forked end .of-the shipper arm m engages the groove between the collars k and k of the clutch K 011 shaft E, and its hub is provided with the downwardly projecting lug a and in like manner the forked end of the shipper arm m e11- gages the groove between the collars 7c and k of the clutch K on shaft B, and its hub is provided with the lug n all as shown in Figs. 2 and 6. The hubs of the shipper arm m and the collar Z are surrounded by the spring m the tension of which tends to press said shipper arm hard against the collar Z. The hubs of the shipper arm m and the collar Z are surrounded by the spring 'm which presses the shipper arm m toward the collar 1, and in like manner the hubs of the shipper arm m and the collar Z are surrounded by the spring m which presses the shipper arm toward the collar Z all as shown in Figs. 1 and 2. I

The shaft F projects through a chambered hub 11 of the frame A and through the double cam-faced cylindrical collar a, secured in a fixed position to said hub, and has firmly secured thereto so as to rotate therewith the two cylindrical cams b and b arranged one at each side of the fixed cam a (see Figs. 20 and 21) and has its outer end squared. To this squared section of saidshaft is fitted so as to be easily detached therefrom the hand lever O, by depressing which the shaft F may be partially rotated and movedendwise toward the left of Fig. 2 a distance equal to the throw of ,"said cam b carrying with it the collars Z,-" Z Z and Z the shipper arms m, m and m and the springs m m, and m said shipper arms m, m, and 'm 2 moving the male clutch sections K, K and K towards the left of Figs. 1 and 2 into engagementwith the female clutch sockets formed in, or connected with the gears b, e, and d as will be more particularly described hereinafter.

The shaft J has secured thereon, in fixed positions, the locking segments 0, 0 and 0 constructed and arranged to be moved into positions at the right of the lugs a, n, and n of the shipper arms m, m, and 'm when said arms are.moved toward the left of Figs. 1 and 2 with the shaft F as above described, and to lock said shipper arms against move ment towards the right of said figures when said shaft F is returned to its normal position by raising said lever O. The shaft J also has secured thereon so as to rotate therewith the cam 0 and the locking arm 0 provided with the shoulders o and 0, (see Figs. 5- and 6) and has secured upon its lefthand end the lever P, the oflice and operation of which will be hereinafter decsribed.

The shaft D extends through the frame A to a considerable distance, has fixed thereon, just outside of the hub of said frame, the collar D which projects over said hub and has formed in the inner surface of said overhanging portion, the annular groove (1 which serves to catch any oil that may drip from the outer end of the bearing of said shaft (see Fig. 13). lar D the shaft D is made cylindrical for about two inches, more or less, in length, and has cut through it the slot D The slot D is partly covered by the collar D provided on its outer end with the annular lip (Z and upon its inner end with the thin sleeve-like hub d through which is cut a slot coinciding with the inner portion of, but of less length than the slot D in said shaft D. The shaft D, from the point 5 to the point 6, is made tapering and flat sided, or nearly square in cross section, as shown in Figs. 13 and 14,

'and from the point 6 to its end it is made cylindrical and of a diameter somewhat less than the thickness of the smallest end of the tapered portion and upon this cylindrical portion is fitted the cylinder D provided near its inner end with the inwardly projecting annular flange d which encompasses the cylindrical end of the shaft D, and between said flange d and the head (1" secured to the end of saidshaft, said shaft is surrounded by the coiled spring (Z which tends to press said cylinder D towards the frame A.

D, D are lags of metal or wood, as preferred, fitted to the tapered flat sides of the shaft D and having their outer surfaces concentric with the axis of said shaft and their end portions reduced in thickness to ermit the inner end of the cylinder D and t e annular lip d to extend over said lags to retain them in lace as shown in Fig. 13. The outer su ace of the lags D may be parallel to the tapered surface of the shaft D as shown in Fig. 13 or parallel to the axis of said shaft, as shown in Fig. 22, for winding tapered, or cylindrical cops, or both. The'se lags D constitute'the mandrehsurface upon which the cop is to be wound.

The shaft or rod H is secured in a fixed position in the frames A and A to serve as a tie rod between said 'frames, but extends beyond the frame A and has loosely mounted thereon a pair of two-armed levers H H in hearings in the lon arms of which is mounted the light roll the periphery of which rests upon the mandrel D or the cop bein wound thereon as shown in Fig. 3, in-

project toward and abut against each other Just outside of the col-,

The outer or movable ends of said arms h are connected by the rod h and each of said hubs 72? has mounted thereon a s )iral spring it one end of which is connecte to an eye e formed on said hub and the other end is connected to the rod h in such a manner that the tension of said springs will tend to lift said rod and the outer ends of the arms h and keep said arms in contact with the limiting pins e set in the short arms of the levers H all as shown in Figs. 1, 2 and 3.

The shaft or rod H has firmly secured to each end thereof in a normally fixed but adjustable position a radius arm R, the outer ends of which are connected by the rod R upon which is fitted so as to be movable ending R composed of the two cylindrical hubs q and (1 the axes of which are at right angles to each other but in different horizontal planes as shown in Figs. 1, 2, 3 and 4.

The sleeve p has mounted thereon between the collar p and nut p so as to be movable about said sleeve, the thread or twine guiding and delivering arm S, said arm being provided with the short arm 7", the forked end of which engages the rod b and is operated upon thereby to retain the twine guiding arm S in engagement with the periphery'of the cop as shown in Figs. 1 and 3. the arm S is provided with a transverse dovetailed groove in which is fitted the porcelain or hardened steel block S having a convex bearing surface to rest against the cop and provided with a twine guiding eye S extending through the center of said convex surface, and also through the lower end of the arm S as shown in Figs. 2, 16 and 17. The hub q of the casting R sleeve-like hub (1 fitted to the cylindrical-lever T, the lower end of which is pivoted to the reci rocating carriage T mounted upon the guir e rods tt, supported at one end in bearings in the frame A and at their other ends in the stand T. The carriage T is made in two parts t and t", the part If being adgust ably secured to the part t by means 0 the bolts ss,. which pass through the slots t t 'form ed in the art It, and screw into The/lower end of has pivoted thereto the i the part t as shown in Figs. 2 and 5. This adjustment ofthe art t on the part t provi es a meansfor a j usting the length of traverse of the guide arm S lengthwise of the cop. The part t of the carriage T has setin its inner side two studs upon which are mounted the rolls to -u, upon-Which the cam L acts to reciprocate said carriage T as shown in Figs. 1, 2 and 5. The lever T has fitted thereon so as to be Intermediate of the arms thereof and each of I movable endwise thereof, the sleeve T having said hubs has loosely mounted thereon, so "i formed thereon the hub T provided on its as to be movable about said hub, an arm hfi l rear with the pintle u tofit a bearing in the I toe, as shown in Figs. 2, 3 and 6.

vertical fulcrum bar U and also with the annular lip 11? which engages two segmental grooves formed in said bar U as shown in Fig. 5, said pintle u forming the fulcrum about which the lever T moves when the carriage T is reciprocated.

The fulcrum bar U is mounted in a suitable bearing in the stand or bracketU formed in one piece with, or firmly secured to, the frame A, and is movable vertically therein by means of the cam or lifter toe U mounted upon the stud a setin the frame A and constructed and arranged to act upon the roll a mounted on a stud set in the lower end of the plate U pivoted at its other end to said bar U, said plate fitting and just filling a. recess formed in the side of said bar, and normally remaining in the position shown in Fig. 6, and in full lines in Fig. 18. The plate U may be moved about its pivot towards the rear as indicated in dotted lines in Fig. 18 to permit the return of. the lifter toe U to its original position as shown in Fig. 6, but cannot be moved about said pivot towards the front,

: beyond a perpendicular position, because of the stop u, (see Fig. 18.)

The stand or bracket U has cut through its front portion the slot U for the passage of the hub T and to permit said hub to be raised with the fulcrum bar U, as shown in Figs. 2 and 6. The cam or lifter toe U has formed on its side towards the frame A the shoulders 12 and t which engage respectively with the lower ends of the stop levers v and v at the proper. time to limit the movement of said lifter toe when operated by the descent of the weight Wsuspended from the handle U", connected to said lifter The levers v and 12 are mounted side by side upon the stud 12 set in the frame A and the upper arm of the lever 22 is pressed'into contact with the cam 0 by the coiled spring if surrounding the screw stud 1; between said lever and the bracket U as shownin Fig. 6. The upper end of the lever '02 is pivoted to'the end of the rod w, said rod being in turn connected by a link 20 to the locking arm V mounted upon and movable about the shaft F near the frame A and provided with the hook-like shoulder w When the shoulder 0 of the arm 0 is raised to a given point by the rotation of the shaft J in the direction indicated by the arrow on Fig. 3, caused by the rise of the roll H as the cop is built up, the shoulder to is moved toward the front of the machine by the reaction of the spring to surrounding the rod w between the bracket U andthe push button w secured to th outer end of said rod, said bracket U being slotted for the passage of said rod w as shown in Figs. 2 and 6. The bed plate A may be mounted upon legs A as shown in Fig. 3 or it may rest upon a bench.

pulley B and locate saict V is a bracket bolted tothe end frame A and projecting toward the front, is provided with two ears 3 y, in bearings in which is mounted the sheave X. Said bracket is also rovided with the u wardly projecting osses y -y in each 0 which is set a stud g u on which is mounted a sheave X A spoo W is mounted upon an arbor in any suitable manner, and from this spool the twine y? is drawn to be wound into a cop, said twine tween the s eaves X and through the twine guiding eye .9 to the mandrel or cop.

vThe shipper rod J 1 operates in an enlarged bearing in the inner end of the hub (i on the frame A (as shown in Fig. 19) and in the frame A so as' to be movable endwise therein and carries at one end a shipper fork (1 one prong of which is shown in Flg. 1' while the other prong is shown in Fig. 4. The opposite end of said rod is provided with the looped handle J and between said handle and the chamber of the hub a said rod is made flat sided and is rovided upon its under edge with the shou der a which engages the lower edge of the opening in the frame A to lock said shipper rod in position with the driving belt'upon the tight or driving The rod J has secured thereon the collar (i andis surrounded between said collar and the hub of by the spring a the ten- -sion of which will move said rod toward the right of Fig. 1 when the handle end of said rod is lifted to disengage the shoulder a from the frame A. Y

When it is desired to build a belt or section of less length than the main body of the cop of the cop, the shaft D is moved the desired distance towards the left of Figs. 1 and 2 and the traverse of the twine-guiding arm is reduced. and automatically moved toward the left of Figs. 1 and 2 at the desired time in the building of the cop, two collars d cl are secured on said shaft between which collars said shaft is embraced by the arm D. Said arm assing over the sheave X, be'

To enable said shaft D to be readily belt at one side of the center D is mounted upon and movable endwise of the shaft I and the rod I and has fitted to a threaded bearing therein the stop screw (1 the left hand end of which abuts against the lug d on the cylinder D This cylinder D is mounted upon the shaft I so as to" be movable about its axis to cause the lug d to' be moved upwardly from the ath of the stop screw d but is-' prevented rom being moved endwise thereon by the collars c and 0 By this means the shaft D is maintained in its normal position, or the position shown in the drawings, until the lug d is moved, around the aXis of the shaft I to disengage it from contact with the stop screw d. Then the tension of the s ring 61 surrounding the shaft I between t e hub of the arm D and the collar fixed on said shaft I will move said" arm D and the shaft D to wards the left of Figs. 1 and 2 until arrested by the hub of the arm I) coming in contact with the collar 0 adjustably secured .upon said shaft I as shown in Fi s. l and 2.

The movement of the ug d around the axis of the shaft I to disengage it from contact with the stop screw d to permit the reaction of the spring d to move the arm D and the shaft D toward the left of Figs. 1 and 2 is accomplished by the upper end of the fulcrum bar U COI111IIO' in contact with and moving the .arm e about the axis of said shaft, when said bar is moved upward to adjust the fulcrum of the lever T, and thus diminish the travel of the twine guiding arm S; the cylinder D, the lug d and the arm 6 being formed in one piece. When the shoulder 12 has come into contact with the lever o the lifter toe U has moved the fulcrum bar U into contact with the arm e to cause ashifting of the shaft D. i

I The arm 6 of the cylinder D is so con: structed as to over-balance the lug (i so that when the fulcrum bar U descends and the shaft D is returned by the hand of the operator. to the position shown in the drawings,

the cylinder D will be turned upon its shaft I by the force of gravity to move the lug d into a position to be engaged by the end of the sto screw d and is registered in this position y shoulders on D an d c coming in corrtact, when said stop screw has been moved towards the right by the retraction of the shaft D k The gears a, d, and e, on the shaft B are so proportioned to the gears a, d and e, on the shaft E, with which they respectivelyengage, that each pair, when engaged by the proper clutch or clutches, will impart to said shaft E a different speed from that imparted thereto by either of the other pairs of said gears. The gear 0 on shaft E is one-half the size of gear 0 on the camshaft C, and the.

gear 6 on shaft B is twice the size of the gear b on the shaft G. As the gears h 2', i and j connecting the shafts G and D arepropors tioned relative to each other'as follows, viz:

the diameter of the geari being ten-elevenths of the gear h and the diameter of the gear i bein equal to eleven-twelfths of the gear j, it f0 lows that the shaft D will make one hundred and twenty-one reyolutions while shaft G is making one hundred and twenty revolutions. In this connection it is to be noted that "the co) hereinafter described is wound with a ban or shorter section formed centrally thereon which operation does not require the endwise movement of the wind ing shaft D previously described; and further, to simplify the description of the operation of the machine the second and third sections of said cop are differentiated by changing the number of reciprocations ofthe uide arm at predetermined times. The ourth section of said cop is difierentiated from the previous sections by changing the finish of t e third section thereof.

The operation of my invention is as followsi Assuming that it is desired to begin to build a new cop having four sections of equal length and a band or fifth section of less length wound centrally thereon, the first thingto be done is to remove the cop that has previously been formed and is still upon the mandrel. To accomplish this the roll H is raised until the arm 0 on the shaft J is moved upward about the axis of said shaft sufficiently far to permit the shoulder 10 of the lockingarm V to pass beneath the shoulder- 0 or o, of said arm 0 whereby said roll will be held in'said raised position until released. The operator then drives a tapered key of suitable width into the slot D between the collars D and D on the shaft D to move the collar D the cylinder D and thelags D towards the left end of the shaft D against the tension of the spring d when the lags D will collapse and permit the cop to be easily removed. The tapered key is then removed from the slot D when the tension of the spring d will return the cylinder D, lags D and the collar D to their normal positions, as shown in Fig. 13. The hand lever O is then pushed downward to move the shaft F endwise toward the left of Fig. 2 by the ac tionof the cam b on collar a, thus moving the ship er forks m, m and m and the clutches IL K and K in the same direction causing said clutches to engage the gears b and e on shaft B and the gear d on shaft'E,

respectively. The handle U and the weight W are then raised by thev operator to' place the cam or lifter toe U in the position shown in Fig. 6 this movement of the cam or lifter toe U causing the member U to be moved about its pivot into the position shown in dotted lines in Fig. 18, said member U returning by gravity to its normal position as soon 'as the lifter toe U passes-beneath it. Then the push button to is moved by hand inward to d'isenga e the shoulder w of the hook arm V. from eneath the arm'o, when the force of gravity will cause the roll H to descend into contact with the mandrel,

thereby moving the shaft J about its axis in the dll'BClJIOIl opposite to that indicated by the arrow on Flg. 3 and carrying the locking segments 0, 0 and 0 respectively, into p0 .sitlons immediately to the right of the lugs n, n, and a on the hubs, respectively, of the shipper arms m, m and m This movement of the shaft J causes a downward movement of the hook P thereby releasing the shipper J so that it can be moved by hand to the left of Fig. 19 and returned by the operator to its locked position as shown in said figure. The lever O is then raised, partially turning the shaft F, when the cam 12 acting upon the Q nonrevoluble collar a causes said shaft to be moved towards the right of Fig. 2 into the position shown in Fig. 2 compressing the simply shipping the driving belt upon the tight pulley B With the parts of the machine in the positions above described, if motion is imparted to the shaft B, motion will be imparted to the cam shaft C through the gears e, e, the shaft E, and the gears c and c and to the shaft D through the gears b, b, shaft G, and the gears W, i, 7?, and y', having diameters relative to each other as hereinbefore stated, and as the gear 6 on shaft B is only half the size of the gear 6 on shaft E and the gear 0 on shaft E is one-half the size of gear 0 on shaft C, said shaft C and the cam L will make only oneeighth as many revolutions as the shaft G, thereby reciprocating the twine guiding arm S at such a speed relative to the revolutions of the shaft D as to wind the twine upon the mandrel in four convolutions to the length of the cop. This is continued, the twine making four convolutions in the length of the cop, reversing when the ends of the cop are reached and winding in the opposite direction the same number of convolutions to the length of the cop and in each direction laying the twine of one helix in near proximity to the preceding helix until a section of the desired diameter has been wound, and the roll H has been raised, by the building up of the co to a sufiicient distance to rotate the shaft; until the locking segment 0 is moved from engagement with the lug n when the reaction of the s ring m moves the shipper arm 'm and with 1t the clutch K towards the right of Figs. 1 and '2, causing the'clutch K to be disengaged from the gear 6, and engaged with the gear 65." The gear d being two-thirds the size of the gear 01 on shaft E, the cam shaft C now rotates one-sixth the speed of the shaft G and causes the twine guiding, arm to deliver the twine upon the cop in three convolutions to the length of the cop in each layer in building up thesecond section of the cop.

I When the second section of the cop has been built up to the desired diameter, and 1 the roll H? has been raised thereby a sufficient height to turn the shaft J about its axis to the point where the locking segment 0 is removed from the path of the lug m the reaction of the spring m moves the shipper m and the male clutch section K towards the right of Figs. 1 and 2, causing said clutch portion K to be disengaged from the gear (l on the shaft E and engaged with the gear a on said shaft E, thereby connecting said gear a to said shaft and causing said shaft to revolve therewith. The gear a being fast on the shaft B and of equal diameter with the gear a on" the shaft E, the cam shaft C will make one revolution to four revolutions of the shaft G, and the twine guiding arm S will be reciprocated at such a speed relative to the revolutions of the mandrel or cop shaft D that the twine will be wound upon the cop in two convolutions in the length ofthe cop, which number of convolutions is maintained until the third section of the cop has reached the desired diameter.

When the roll'H has been moved upward by the building of the cop till the locking segment 0 is removed from the path of the lug n the reaction of the spring m moves the shipper arm m and the male clutch section K towards the right of Figs; 1 and 2, causing said clutch section to be disengaged from the gear I), rendering the gears b and b inoperative, and to engage with the gear 0 causing it to revolve, with the shaft B. Motion is now imparted from the shaft B to shaft G through gears 0, c 0 g, h, and h so proportioned that, whereas previously the shaft G made exactly two revolutions to one of the shaft B, both now rotate approximately alike, and since the rotations of the cam shaft C and cam L remain the same as when winding the third section of the cop said cam will now make substantially one-half the number of revolutions made by the shaft G When the fourth section has reached the V desired diameter the lever '0 has been acted upon to move its lower end inward to a sutficient distance to disengage it from the shoulder v of the'lifter-toe U when the force of gravity acting upon the weight 1N will cause the lifter toe to be moved about its axis in the direction indicated by the arrow on Fig. 6 until 'arrested by the shoulder 12 coming in contact with the lower end of the lever 42 thereby liftin the fulcrum bar U and the. sleeve T a istance equal to the throw of said lifter toe. This action, the changed length of traverse being pro erly determined, shortens the traverse the twine guiding arm S which then delivers the twine upon the cop in such a manner that a band or section of less axial length than the movement of the lifter toe U till the previous sections is formed centrally upon the ourth section, made'up. of a series 0 layers each having the same number of helixes and each helix. having the same number of convolutions as in the immediately preceding section of the cop, the helixes being closer together on account of the shortened space traversed by the twine guiding arm.

The band having reached the desired diameof wraps may be such on a section wound immediately prior. to the shorter section wound thereon that when the traverse of v the arm S is shortened, said Wraps will crowd and possibly'at times overlap, and therefore it may be desirable to wind the wraps of the said inner section farther apart, than in the previously wound sections in which case it will be only necessary to shorten the distance traversed by the guide arm to wind another cop section.

While cops may be wound in sections by alternately changing the distance traversed by the guide arm S, the cop sections so formed are of unequal axial length in the same cop and cannot be so compactly Wound nor contain as much twine in the same space as whenwound as herein described.

In practice it has been found that when during the winding of a plurality of cop sections the number of rotations maintained by the winding shaft D is relatively one more than a number that is exactly divisible by the number of complete reciprocations meanwhile made by the guide arm S (the length of said reciprocations remaining unchanged,

throu hout said layers), the several complete layers of double thickness of twine in such cop sections as are wound under these conditions in a cop will consist of the same maximumfnumber of wra s of twine. To

. illustrate, as herein descri ed, the shaft D rotates 121 times, or one more than 120, which latter num'ber is exactly divisible by 15 the number of times the guide arm S is meanwhile reciprocated lengthwise of the the mec again cop during the winding of each completed layer of double thickness in the first cop section; by,20 the number of times said guide arm S is likewise reciprocated during the winding of each com leted layer in the sec-v ond cop section; an by 30 the number of times said guide arm S is in like manner reciprocated during the winding of each completed layer in the third co section. In

each completed layer of doub e thickness of' twine of said cop sections 120 wraps of twine will be wound, said layers of the first cop section each consisting of 30 helixes each having four convolutions in its length upon the cop; said layers of the second cop section each consisting of 40 helixes each having three convolutions in its length upon the cop; and said layers of the third cop section each consisting of 60 helixes each having two convolutions in its length upon the cop.

When the gears b and b are inoperative, motion is imparted to shaft G through gears c, c, 0 g, h and h which are so proportioned relative to each other that a different fixed ratio will be maintained between the relative rotations of the shafts B and G during the winding of the. succeeding layers and since the gears by which said ratio is maintained are not connected with the shaft C it is obvious thatany desiredratio may be estab-- lished by properly proportioning said gears, as for instance said change or ratio may affect the number of rotations of the winding shaft causing the several layers to be wound thereafter at a decreased circumferential speed as heretofore described; said change of ratio may affect the number of helixes wound in each completed layer wound thereafter;,said change of ratio may affect the number of helixes and the number of convolutions in each of said helixes in each of the completed ,layers wound thereafter; or said change of ratio may simultaneously include two or more of the above changes. The

abrupt changes of ratio in the relative movements of the winding shaft and' guide arm made when changing from one cop section to another may occur anywhere in the length of the copand the degree of abruptness depends u on the rapidity of the movement of fianism for changing said ratio, and it also momentarily causes a slight deviation in the regularity of the winding, hence, for the purpose of description herein, when reference is made to, the character of the winding, after a change, it refers to the portion that is wound when said ratio has become fixed.

When reference is made to a completed layer of double thickness of twine it refers to so much of the twine as is wound while the ratio is fixed, from the time the twine passes over a fixed point anywhere in the length of the body of the cop on its surface until it asses in the same direction over the same ed point'but it does not necessarily convex surface, relatively exposes the great begin and stop at one of the ends of the cop. Agnln when the word number is used to designate the number of windings or 0011- volutions in a helix in its length upon the cop it refers to a close approximation to said number for it is evident that the number of (-onvolutions in a helix cannot be exactly four, three, two or one but must be slightly more or less than the designated number to allow the twine in one helix to pass and lie in near proximity to the immediately preceding helix.

The pairs of gears c and d and d a and a, and e and may be differently proportioned to make the number of convolutions in the axial length of the cop, in any section thereof, either an integer or a mixed number and they may be so arranged that the com pleted layers may consist of a larger or smaller number of convolutions in the axial length than in the immediately preceding or succeeding section, as for instance, the first section may have three convolutions, the second section two, the third section one and one-half, and the fourth section one, or two, convolutions in its axial length.

It will be seen that the bearing or inner surface of the free end of the twine guiding arm is so shaped and the arm is so mounted that in its traverse lengthwise of the mandrel it will readily mount the ends of the raised portions of the cop formed by the layers of.

narrower width wound thereon, and since the delivery eye is central of the convex surface thereof the point of delivery is always in close proximity to the surface of the copduring the winding. The area of contact is reduced to a minimum which is a desirable feature inasmuch as it decreases the chafing caused by the face of the guide arm rubbing and sliding againstthe cop, and further, the

est surface to the cooling effect of the current of air clrculating around the surface of the it to disengage the shoulder a from the hub a when the tension of the spring a will move the shipper rod and ship the driving belt upon the loose pulley, not shown, and thus arrest the operation of the machine.

' By moving the free end of .the hook P toward the front of the machine afterthe roll II has been raised from contact with the cop and locked in such elevated position the shipper can be used to operate the machine while said roll is retained in such locked position. the shipper arm J only when the cop is ap- The hook I need be in contact with proaching completion; and attaching said hook in an adjustable position permits mechanical arrest of the operation of the machine whenever desired. i It is obvious that it can be so adjusted in a position as to limit the duration of the winding of a section differentiated from a previously wound cop section by change in the relative rate of movement of the guide arm or winding shaft; by

change in the len th of traverse of the guide; by shifting the winding shaft endwise; singly or two or more concurrently, and in the desired sequence such as described. Claims. 1.
